Paraffin route method, which a paraffin is used as a solvent instead of TOPO, is relatively new method to synthesize nano-particles using a solvent with high melting point. Thus, this method is relatively clean and cheap.. In this study, CdTe QDs was synthesized by using a paraffin method.First, the Cd precursor solution was prepared by dissolving CdO in a mixture of oleic acid and paraffin liquid. Then the Te precursor solution was prepared by dissolving Te powder in a mixture of trioctylphosphine (TOP) and paraffin liquid. After mixing both solutions, the solutions were stirred to grow CdTe NCs. Finally the CdTe NCs were separated by centrifugation and washed by methanol. As-synthesized CdTe NCs were investigated by various methods including XRD, TEM, PL and EDS.
